Brooks' Insulator and the C.P.R.R. Telegraph.
A LETTER from F. L. Vandenburgh, Supt., dated Sacramento, May 22 says:
"I worked my line on Brooks' Insulators from Promontory to Wadsworth, 550 miles, through heavy rain, clear of escape, when M. P. could not work to Corrin, 40 miles, through the same storm. They use glass and bracket."
